Common table expressions can also be used with the SELECT, INSERT, DELETE, and CREATE VIEW statements. For information about table hints, see , 'expression' should be prefixed with the capital letter 'N'.
For more information, see Specifies one or more table hints that are allowed for a target table. If 'N' is not specified, SQL Server converts the string to the code page that corresponds to the default collation of the database or column.
Specifies that the default value defined for the column is to replace the existing value in the column.If you need more details, I can upload a report with file versions.

Avoid using these hints in this context in new development work, and plan to modify applications that currently use them.
